The partition 15 may be partitioned into a plurality of storage chambers 21, 22, 23, and 24 by the partition 15. The partition 15 may include a first partition 17 disposed to cross the storage chamber 20 horizontally to partition the storage chamber 20 into a upper storage chamber 21 and a lower storage chamber 22, and a second partition 19 disposed to cross the lower storage chamber 22 vertically to partition the lower storage chamber 22 into a first storage chamber 23 and a second storage chamber 24.

The partition 15 having a T-shaped structure by combining the first partition 17 with the second partition 19 may partition the storage chamber 20 into three spaces.

The upper storage chamber 21 partitioned by the first partition 17 may be used as a refrigerating chamber, and the lower storage chamber 22 may be used as a freezing chamber.

The entire lower storage chamber 22 may be used as a freezing chamber. Also, the first storage chamber 23 may be used as a freezing chamber, and the second storage chamber 24 may be used as a refrigerating chamber. Also, the first storage chamber 23 may be used as a freezing chamber, and the second storage chamber 24 may be used as both a freezing chamber and a refrigerating chamber.

However, the storage chambers 21, 22, 23, and 24 may be partitioned in a different manner.

The door 30 may include an upper door 31 configured to open or close the upper storage chamber 21, and a lower door 33 configured to open or close the lower storage chamber 22. On the rear surface of the door 30, a plurality of containers 50 may be installed to store food, etc.

Hereinafter, a case 40 coupled with the rear surface of the door 30, and the containers 50 removably accommodated in the inside of the case 40 and configured to slide by a sliding apparatus to be inserted into or pulled out of the case 40 will be described in detail.

As shown in FIG. 2, a protrusion 41 may be formed on the rear surfaces of both side walls of the case 40, and a fixing groove 35 which the protrusion 41 is inserted into and fixed at may be formed in the rear surface of the door 30.

By inserting the protrusion 41 into the fixing groove 35, for example, the case 40 may be fixed on the rear surface of the door 30 such that the rear surface of the case 40 faces the rear surface of the door 30.

As shown in FIG. 3, an opening 43 may be formed in the front portion of the case 40, and a plurality of container accommodating portions 45 for accommodating the containers 50 may be formed in the inside of the case 40.

In FIG. 3, two container accommodating portions 45 are shown, however, a single container accommodating portion 45 or two or more container accommodating portions 45 may be formed.

The containers 50 accommodated in the inside of the case 40 may be slidingly moved by the sliding apparatus to be inserted into or pulled out of the case 40 through the opening 43.

As shown in FIGS. 3 to 6, the sliding apparatus may include a guide rail 80 formed in both edges of the bottom of each container 50, and a guide portion 70 disposed in the case 40 to correspond to the location of the guide rail 80 and configured to guide the guide rail 80.

The guide portion 70 may be disposed in both edges of the bottom of the container accommodating portion 45 of the case 40, in such a way to be inclined upwardly toward the front end from the rear end.

Since a user may grip a handle 51 that is, for example, upwardly concave from the front lower end of the container 50 to pull the container 50 out of the case 40, the front portion of the container 50 may be lifted upward when the container 50 is pulled out of the case 40.

Since the front portion of the container 50 may be lifted upward when the container 50 is pulled out of the case 40, the guide portion 70 supporting the guide rail 80 of the container 50 may be inclined upwardly toward the front end from the rear end.

The guide portion 70 may guide the side surfaces of the guide rail 80. In the front end of the guide portion 70, a roller coupling portion 71 may be formed to be coupled with a roller 77, and in the rear end of the guide portion 70, a fixing rib 73 may be formed to prevent the container 50 from moving upward or downward.

The roller 77 rotatably coupled with the roller coupling portion 71 may guide the guide rail 80 to enable the container 50 to smoothly slide.

The roller 77 may fix the container 50, while enabling the container 50 to smoothly slide.

The fixing rib 73 may be formed at the rear end of the upper surface of the guide portion 70, and at the front end of the fixing rib 73, and include an edge that may be formed upward in a streamlined shape.

On the lower surface of the fixing rib 73, a supporting rib 85 formed in the container 50 may be supported. Since the upper surface of the supporting rib 85 may be supported by the lower surface of the fixing rib 73 when the container 50 is pulled out of the case 40, the container 50 can be prevented from moving upward or downward when it is pulled out of the case 40.

A streamlined shape 75 formed in the front end of the fixing rib 73 may function to easily separate the container 50 pulled out of the case 40 from the case 40, which will be described in detail, later.

The guide rail 80 may be formed in both edges of the bottom of the container 50 to correspond to the guide portion 70 of the case 70.

The guide rail 80 may be guided by the guide portion 70 and the roller 77 to slide in a front-rear direction.

In the front end of the guide rail 80, a stopper groove 81 may be formed in which the roller 77 is accommodated when the container 50 is accommodated in the inside of the case 40, and in the rear end of the guide rail 80, a stopper 83 may be formed to be fixed at the roller 77 when the container 50 is pulled out of the case 40.

The stopper groove 81 may be formed in the front end of the guide rail 80, and when the container 50 is accommodated in the inside of the case 40, the stopper groove 81 may accommodate the roller 77 therein to fix the container 50.

Since the container 50 is fixed by the stopper groove 81 when the container 50 is accommodated in the inside of the case 40, the container 50 can be prevented from moving in the front-rear direction.

The stopper 83 may be formed in the rear end of the guide rail 80, and fixed by the roller 77 when the container 50 is pulled out of the case 40, thereby fixing the container 50.

Since the container 50 may be fixed by the stopper 83 in the state in which the container 50 is pulled out of the case 40, the movement distance of the container 50 may be limited so that the container 50 is no longer pulled out and stops after it is pulled out by a predetermined distance.

The container 50 may include the supporting rib 85 supported by the fixing rib 73 of the case 40 in order to prevent the container 50 from moving upward or downward when the container 50 is inserted into or pulled out of the case 40.

Since the upper surface of the supporting rib 85 is supported by the lower surface of the fixing rib 73 when the container 50 is inserted into or pulled out of the case 40, the container 50 can be prevented from moving.

An operation in which the container 50 is pulled out and separated from the case 40 will be described in detail with reference to FIGS. 6 to 10.

FIG. 7 shows a state when the container moves in the front direction in the state of FIG. 6, FIG. 8 shows a state when the container according to an embodiment of the present disclosure is pulled out of the case, FIG. 9 shows a state when the front portion of the container is lifted upward in the state of FIG. 8, and FIG. 10 shows a state when the container is separated from the case in the state of FIG. 9.

As shown in FIG. 6, while the container 50 is accommodated in the inside of the case 40, the roller 77 may be accommodated in the stopper groove 81 to fix the container 50, so that the container 50 can be prevented from moving in the front-rear direction when a user opens or closes the door 30.

While the container 50 is accommodated in the inside of the case 40, the supporting rib 85 may be spaced from the fixing rib 73 without being supported by the fixing rib 73. The reason is because while the container 50 is accommodated in the inside of the case 40, the bottom of the container 50 contacts the bottom of the container accommodating portion 45 to be supported by the bottom of the container accommodating portion 45 so that the supporting rib 85 does not need to be supported by the fixing rib 73.

As shown in FIG. 7, if the user pulls the container 50 in the front direction in order to take the container 50 out of the case 40, the roller 77 and the guide portion 70 may guide the guide rail 80 to slide in the front direction so that the container 50 moves in the front direction.

When the container 50 is pulled out of the case 40 in the front direction, the front portion of the container 50 may be lifted upward, so that the front portion of the container 50 is pulled out upward, and the upper surface of the supporting rib 85 contacts the lower surface of the fixing rib 73 and is supported by the lower surface of the fixing rib 73.

As shown in FIG. 8, if the stopper 83 is fixed by the roller 77 when the container 50 is pulled out in the front direction, the container 50 may be no longer pulled out in the front direction and stop.

Since the supporting rib 85 may be supported by the front end of the fixing rib 73 and maintained, the front portion of the container 50 may be prevented from tilting downward.

If the user pulls the container 50 in the front direction while lifting the front portion of the container 50 upward in the state in which the container 50 is pulled out of the case 40, as shown in FIG. 9, the supporting rib 85 may be guided by the streamlined shape 75 of the fixing rib 73 so that the front end of the container 50 may be lifted upward, and thus the container 50 can be easily separated from the case 40, as shown in FIG. 10.

An exemplary embodiment for separating a container from a case will be described with reference to FIGS. 11 to 20.

FIG. 11 is a perspective view showing a state in which a container is accommodated in the inside of a case according to an embodiment of the present disclosure, FIG. 12 is a perspective view showing a state in which a container according to an embodiment of the present disclosure is separated from the case, FIG. 13 shows a state in which a front cover according to an embodiment of the present disclosure opens, FIG. 14 is an enlarged view of a fixing hole formed in the case according to an embodiment of the present disclosure, FIG. 15 shows a lever and a lever case coupled with the container according to an embodiment of the present disclosure, FIG. 16 shows a state when the lever is coupled with the lever case according to an embodiment of the present disclosure, FIG. 17 is a cross-sectional view showing a state in which the lever is coupled with the lever case according to an embodiment of the present disclosure, FIG. 18 shows a state in which a fixing protrusion according to an embodiment of the present disclosure is fixed at a fixing portion, FIG. 19 shows a state when the lever rotates so that the fixing protrusion is released from the fixing portion in the state of FIG. 18, and FIG. 20 shows a state when the container moves in the front direction in the state of FIG. 19 so that the fixing protrusion escapes from the fixing hole through an exit portion.

A configuration in which a case 140 is coupled with the rear surface of the door 30 has been described above with reference to FIG. 2, and accordingly, a detailed description thereof will be omitted.

As shown in FIGS. 11 to 13, a container 150 may be accommodated in the inside of the case 140, and may be fixed in or released from the case 140 by a fixing apparatus 160.

The container 150 may be accommodated in the lower space of the case 140. The upper part of the container 150 may open, and the container 150 may be inserted into or pulled out of the case 140 through an opening 141.

The handle 181 may have a cloven shape such that it can be inserted into the coupling rib 151 formed in the side walls of the container 150. A user may grip the handle 181 to separate the container 150 from the case 140 or to fix the container 150 in the case 140.

The lever 190 may include a plurality of coupling protrusions 194 which will be described later, and the plurality of coupling protrusions 194 may be inserted into and coupled with the plurality of coupling holes 183 to be fixed by the fixing rib 185.

The lever 190 may include the fixing protrusion 191 fixed at or released from the fixing portion 171 of the fixing hole 170, a coupling portion 193 on which the plurality of coupling protrusions 194 coupled with the plurality of coupling holes 183 formed in the lever case 180 are formed, an extension portion 195 extending from the coupling portion 193 and having a length that is longer than the width of the handle 181, a pressing portion 197 formed in the extension portion 195 together with the fixing protrusion 191, and an elastic portion 199 formed below the extension portion 195 and having elasticity.

While the container 150 is accommodated in the inside of the case 140, the fixing protrusion 191 may be fixed at the fixing portion 171 of the fixing hole 170 to fix the container 150 in the inside of the case 140, and when the user presses the pressing portion 197, the fixing protrusion 191 may move downward to be released from the fixing portion 191.

If the user pulls the container 150 in the front direction, the fixing protrusion 191 released from the fixing portion 171 may escape from the fixing hole 170 through the exit portion 173, and if the fixing protrusion 191 escapes from the fixing hole 170, the container 150 may be separated from the case 140.

The lower portions of the plurality of coupling protrusions 194 may be inserted into and coupled with the plurality of coupling holes 183 of the lever case 180, and the upper portions of the plurality of coupling protrusions 194 may be fixed by the fixing rib 185 such that the plurality of coupling protrusions 194 do not escape from the plurality of coupling holes 183.

The extension portion 195 may extend from the coupling portion 193, and have a length that is longer than the width of the handle 181. Accordingly, when the user presses the pressing portion 197, the extension portion 195 may enable the lever 190 to rotate with respect to the plurality of coupling protrusions 194 without contacting the handle 181.

The pressing portion 197 may be formed at the end of the extension portion 195 extending from the coupling portion 193 on which the plurality of coupling protrusions 194 are formed, together with the fixing protrusion 191. When the user presses the pressing portion 197, the lever 190 may rotate with respect to the plurality of coupling protrusions 194 so that the fixing protrusions 191 rotate upward or downward with respect to the plurality of coupling protrusions 194.

The elastic portion 199 having elasticity may be disposed below the extension portion 195 to contact the handle 181. When the user presses the pressing portion 197, the lever 190 may rotate with respect to the plurality of coupling protrusions 194 such that the pressing portion 197 moves downward, and accordingly, the elastic portion 199 may be compressed to store an elastic force. If the user removes a force pressing the pressing portion 197, the lever 190 may rotate with respect to the plurality of coupling protrusions 194 by the elastic force so that the pressing portion 197 moves upward.

Thereafter, operation of pulling the container 150 fixed in the inside of the case 140 out of the case 140 to separate the container 150 from the case 140 will be described with reference to FIGS. 18 to 20.

As shown in FIG. 18, while the container 150 is accommodated in the inside of the case 140, the fixing protrusion 191 of the lever 190 may be fixed at the fixing portion 171 of the fixing hole 170 formed in the case 140 to prevent the container 150 from escaping from the case 140.

As shown in FIG. 19, if the user presses the pressing portion 197, the lever 190 may rotate such that the pressing portion 197 moves downward, and the fixing protrusion 191 may also rotate downward together with the pressing portion 197.

If the fixing protrusion 191 rotates downward, the fixing protrusion 191 may be released from the fixing portion 171 so that the container 150 can move in the front direction.

If the user moves the container 150 in the front direction when the fixing protrusion 191 is released from the fixing portion 171, as shown in FIG. 20, the fixing protrusion 191 may escape from the fixing hole 170 through the exit portion 173, so that the container 150 may be separated from the case 140.

Since the width of the exit portion 173 increases gradually toward the front direction from the fixing portion 171, the fixing protrusion 191 may be not caught by the fixing hole 170 although the front portion of the container 150 is lifted upward, when the container 150 moves in the front direction, so that the container 150 can be easily separated from the case 140.

An exemplary embodiment of separating the container 250 from the case 240 will be described with reference to FIGS. 21 to 26.

FIG. 21 is a perspective view showing a state in which a container is accommodated in the inside of a case according to an embodiment of the present disclosure, FIG. 22 is a perspective view showing a state in which a container according to an embodiment of the present disclosure is separated from the case, FIG. 23 is a perspective view showing the bottom of the container according to embodiment of the present disclosure, FIG. 24 is a perspective view showing a state in which the container according to an embodiment of the present disclosure is accommodated in the inside of the case, FIG. 25 shows a state when the container is pulled out of the case in the state of FIG. 24, and FIG. 26 shows a state when the container is separated from the case in the state of FIG. 25.

As shown in FIGS. 21 to 23, a case 240 may be fixed on the rear surface of the door 30 such that the rear surface of the case 240 faces the rear surface of the door 30, and in the front part of the case 240, an opening 241 may be formed.

A container 250 that is inserted into or pulled out of the case 240 through the opening 241 may be accommodated in the inside of the case 240, and the upper part of the container 250 may open.

The container 250 may be positioned below the ice-making apparatus 27 when the door 30 is in a closed state, and at this time, the container 250 may be used to store ice cubes made by the ice-making apparatus 27 (see FIG. 1).

The container 250 accommodated in the inside of the case 240 may slide by a sliding apparatus 260 so as to be inserted into or pulled out of the case 240 through the opening 241.

The sliding apparatus 260 may include a guide portion 270 formed in both edges of the bottom of the container 250, a guide rail 280 formed in the case 240 and configured to guide the guide portion 270, and a separating portion 290 formed in the front end of the guide rail 280 and having a width that is wider than that of the guide rail 280, wherein the upper part of the separating portion 290 opens.

The guide portion 270 may be guided by the guide rail 280 to slide in the front-rear direction, and according to movement of the guide portion 270, the container 250 may slide in the front-rear direction to be inserted into or pulled out of the case 240.

The container 250 may include a connecting portion 271 connected to the bottom of the container 250, and a guide 273 formed in the lower end of the connecting portion 271 and having a width that is wider than that of the connecting portion 271.

The width of the guide rail 280 may be narrower than that of the guide 273 in order to prevent the guide 273 from escaping from the guide rail 280, and the width of the guide rail 280 may be wider than that of the connection portion 271 so that the connecting portion 271 can move in the front-rear direction along the guide rail 280.

Since the guide 273 of the guide portion 270 moving along the guide rail 280 is positioned below the guide rail 280, the guide portion 270 can be prevented from escaping from the guide rail 280.

The separating portion 290 may be formed in the front end of the guide rail 280, and have a width that is wider than that of the guide rail 280.

The separating portion 290 may include a fixing portion 291 configured to fix the guide portion 270 moving in the front direction along the guide rail 280 so that the container 250 can be fixed.

The fixing portion 291 may include a catching portion 293 to fix the guide portion 270, and an inclined surface 295 formed in the upper surface of the catching portion 293 and inclined upward toward the front end from the rear end.

Hereinafter, operation in which the container 50 is separated from the case 40 after it is pulled out of the case 40 will be described in detail with reference to FIGS. 24 to 26.

If the user moves the container 250 in the front direction as shown in FIG. 25 when the container 250 is accommodated in the inside of the case 240 as shown in FIG. 24, the guide portion 270 may move in the front direction along the guide rail 280 so that the container 250 is pulled out through the opening 241 (see FIG. 22).

The container 250 pulled out through the opening 241 may be fixed by the guide portion 270 stopped by the catching portion 293 so that the container 250 can be prevented from moving in the front direction.

If the user moves the container 250 in the front direction while lifting the front portion of the container 250 upward when the guide portion 270 is fixed by the catching portion 293, as shown in FIG. 26, the guide portion 270 may climb over the catching portion 293 to move along the inclined surface 295.

The guide portion 270 moved along the inclined portion 295 may escape from the case 240 through the opened upper part of the separation portion 290 so as to separate the container 250 from the case 240.

Since the separating portion 290 may have a width that is wider than that of the guide 273, the guide portion 270 can be easily separated from the case 240 through the opened upper part of the separating portion 290.

According to exemplary embodiments of the present disclosure, since the container can be easily separated from the door, it is possible to efficiently use the inside space of the container.
